GeoJSON to KMZ Converter
Publish web map data as a single, self-contained KMZ file that anyone can open in Google Earth without a browser. Runs locally, no upload.
Your files never leave this tab
There is no upload. Files are read by the code already running on this page, processed in memory, and handed straight back to you as a download. This tool has no server that accepts your data and nothing is written to storage.
Want proof? Turn off your Wi-Fi, then convert. It still works, because the work happens on your device.

Why convert GeoJSON to KMZ
GeoJSON lives happily in a web map, but it is not something a non-technical person can just double-click and view. Converting to KMZ packages the same geometry into a format Google Earth opens directly, useful when the person you are sending it to is not a developer.
Curious how the conversion itself works with nothing ever uploaded? Read how TrailConvert works.
